xfsdump does not compress stuff.

Option 2 will nullify all of xfsdump's fault tolerance features when
writing to tape.  In other words, if there's a tape error or you hit the
end of tape, xfsdump can't recover.

I understand of course that this might be fine for some, but many sites
don't like to take chances with their backups.  Just thought I'd mention
this in case it was an issue.
